8297 Is from a few years back and its even getting expensive 200+$(new in a box will be even more)
8466 Is very out of date and is a collectors item today even a used one is hard to find under 350$. this set is over 10years old now? I know i would love to have this kit just for the wheels but the cost of this is just way to much, if the OP is in the EU it may be cheeper as finding this kit in the USA is very hard today. shipping this very heavy kit over seas will be very costly as well.
Not that these are bad choices but you wont get one from Lego. also a kit that is over 10 years old will have age issues.
Not sure as the OP never stated a cost he would be willing to spend , but I know for many today, kids more over, spending 300+ on a technic kit is alot of cash. Other issues is yo need to be 18 and over to buy at bricklink or have a parent do the purchase.
If you look up "Lego trial trucks" you find so much that it will take a week just to see them all.
